,Be itjlmown that I, JOHN SHAW, a citizenl of the United States, residing in New Haven, county of New HavemState of Connecticut, have invented certain new and useful Improvements in Locks, f which the following is a full, clear, and exactfdescription. V y l f This invention relates lto locks', and more particularly to locks having a latch bolt retractable by inner and outer manual retracting devices, and provided withl stop work,

or night latch mechanism, fordogging'the outer retracting device. In some Vinstances, locks of this character have been successfully attacked by throwingv off the night latch mechanism by means of a fthin' blade be pushed in in this manner 'bya burglarV or sneak thief, the door can be immediately opened without further difficulty, by-.manipulation of the outer knob. According'to my present invention, I jproposetofovercome this -drawbackbyproviding means automatically operatedv by "the'closing of the door to dog the outer hub, or its-equivalent, in a direct manner independently Vof the dogging action of the night; latch mecha-v nism, so that the outerknob, or other latch retracting device, will be directly and firmly Vblocked against operation, andlmaintained in this condition,'irrespective .ofthe actuation of the night latch mechanism. In'other words, I provide means auxiliary tothe night latch mechanism to dog the outerl hub independently, which means lcannot be reinderedinoperative, when the door is closed, by the' manipulation of the night latch mechanism, or other possible method'f at- `outer retracting .device only when such operation is desired, means being provided for holding said dogging device in the'inoperative 'position when itis desired to have the door freely openable by manipulation of the Specification of Letters Patent. .:Pat

Theyoh by of ecouter shown). ln the form shown, the latch bolt 2l may also be actuated by means of a lever 27 engaged with the cross-head 23 and adapted to be operated by suitable. key mechanism, which it is not necessary to illustrate. The outer knob may be dogged by means of night latch mechanism cooperating with the outer hub 25, and comprising the usual dogging slide 28, walking beam 29, and releasing slide 30, the slides 28 and 30 being provided with push button heads 28a and 30"L respectively, projecting through the face plate 3l, as shown in Fig. 8. When the door is closed, the latch bolt 2l is automati- Y cally deadlocked in the customary manner by means of a deadlocking lever 32, controlled by a guard bolt or controller 33, projecting through the face plate and adapted to be pressed inward by contact with the strike 34, as shown in Fig. 3. As the controller is forced inward by contact with the strike, a lug or hook 35 carried by a depending plate 36 which engages the lower edge of the lever 32 and normally holds said lever out of the path of the latch bolt) is moved rearwardly to permit the lever 32 to be swung into deadlocking position by means of a spring 37. Y

All of the parts so far described are old and well-known and form, in themselves, no part of my present invention.

ln accordance with my invention, I provide means for dogging the outer hub 25 independently of the dogging action of the night latch slide 28, or its equivalent. This additional, or auxiliary dogging means, may take the form of a lever 38 pivoted in the case at 39, and having at its free end a lug 40 adapted to dog the outer hub by entering the customary notch 25a with which the latter is provided.. The lever 38 may be arranged above the yoke 24 and night latch slide 28, as shown, so as to lie immediately beneath the cap plate. The shank of the lever 38 operates in a notch or cut-away portion 50 of the yoke, as shown more particularly in F 9. ln the embodiment illustrated, the free end of the lever is provided adjacent the lug 40 with an enlargement or head 41 over ying the slide 28, and provided 'with an elongated slot 42 engaged by a pin 43 on said slide, for the purpose which will presently appear. Adjacent the pivot 39, the lever 38 is provided with a laterally projecting arm 44 has/*ing an inwardly turned flange or lip 45 adapted to take over or under the controller lug or hook 35 when the controller is pressed inward, according to the angular position in which the dogging lever is placed. The extremity of the arm 44, having the flange 35, is rounded off at its upper part, as shown at 46, in Fig. 10, and the lower surface of the lug is beveled otf to cooperate with the portion 46, in the manner presently explained. The auxiliary dogging member 38 is normally held out of engagement with the hub 25 bymeans, such as a spring 47, which urges the lever toward the left as far as is permitted by the pin 43 in the slot 42. The spring` 47 may be conveniently formed of a coil. of spring wire embracing the post 39 on which the lever 38 is pivoted, and having an end portion 47X engaged in small notch at the edge of the lever.

l/Vhen the door is open and the night latch mechanism is off, the parts will have the position shown in Fig. l. 0n closing the door, the controller 33 will be forced inward by the strike to deadlock the latch bolt, as hereinbefore described, and as the controller is moved inward its lug or hook 35 will pass freely beneath the flange or lip 45 of the member 38 without affecting the latter in any particular. Supposing that the door is again opened for the purpose of blocking the outer knob, the dogging slide 28 may be readily pushed in to engage the hub 25 in the usual manner. This inward movement of the slide 28 will carry the main portion of the lever 38 to the right by the engagement of the pin 43 with the right-hand end of the slot 42. This new position oi the auxiliary clogging lever, as the slide 28 is engaged with the outer hub, is shown in Fig. 2. If the door is now closed, the extremity of the'arm 44 of the lever 38 will be in such a position as to lie in the path of the inwardly moving controller lug 35. The beveled lower surface of the lug 35 engages the rounded nose portion 46, and pushes the arm 44 downward until the lug 40 is snugly engaged with the notch of the outer hub, as shown in Fig. 3. The parts are so arranged that when the controller is at the limit of its inward movement, 'the lug 40 will be sufficiently engaged with the notch 25a to dog the outer hub in an effective manner, and the lever 38 will be held in its dogging position by the controller, as long as the door is closed. Supposing that a burglar or crook succeeds in throwing off the night latch mechanism by pressing inward the releasing slide 30, as shown in Fig. 4, the dogging member 38 will still be effective to dog the outer knob, and the attack on the lock will be thwarted. lnasmuch as it is impossible for the burglar, in the ordinary course of events, to release the controller 33, while the door is closed, the auxiliary dogging means for the outer retracting device will be safe from attack. The member 38' is housed wholly within the lock case, and it cannot be released from dogging position except by an outward movement of the controller which, of course, is effectively prevented by the strike. Supposing that the parts are in the position Vshown in Fig. 3, the door maybe opened by manipulationof the fin side hub," or by theinser'tion of ai'proper key into' th'e lock fromthe outside', andi-the night latch mechanism-may ,thensbe' released n inthe uSu'aI'Way byfpushingllin the releasing slide 30. This willfpermit'the'vspring f 4:7 to shiftltheclogging-member 38 outof engagement with the vouter hub, and'- asf'the` wherein it will be operatively engaged Vwith the controller when such is desired. When the auxiliary clogging member is in the fully released position ofFig. l1, the extremity of the arm 44Cv ivillbe confined betvveen the controller lug and the shank of thedead e when the controller is pressedv inward, as shoWn'in Fig; 6,vbut

locking lever V32,

When the clogging memberI is held inV its operative position, as shoivnrin- Fig. 3, the lug 35 `Willliel between the lever 32 and the arm 44,' as shown in Fig. 7.
